Removable partial denture production in western Germany

Removable partial denture production in western Germany was studied by analyzing 1,082 photographs taken in consecutive series at five large dental laboratories. The photographic technique was standardized, enabling evaluation of the casts as well as the design of the dentures. Of the casts, 47.2% were maxillary and 52.8% were mandibular. The mean number of teeth present was 6.29 in the maxilla and 6.57 in the mandible. In the maxilla, 52.9% of the molar regions were edentulous; ie, they had distal-extension free-end spaces. The corresponding figure for the mandibles was 72.7%. Most of the maxillary removable partial dentures had a palatal strap or a palatal plate, and most of the mandibular dentures had a lingual bar. Of the removable partial dentures, 53.1% had precision attachments, and 36.1% were retained by clasps only.
